oi France, and residing at Paris, 123 Boule vard de la Gare, France, have invented an- Apparatus for Compressing Sugar or the like, of which the cation. e

The present invention has for its object a. machine for compressing sugar, manu factured in mass, for conversion into lumps following is a specifiof definite weight and size, the machine being adapted to arrange the lumps in order on plates for'conveyance to a drying stove. It is constituted primarily by the combination, about a rotatable table pierced by socket molds of four devices serving for filing, for pressing, for' evacuation of finished lumps, and for cleaning the pressing pistons.

Further, the machine carries means for regulating the capacity of the molds, and the travel of the pressing pistons to the desired height during rotation of the table.

The invention will be described with reference to the accompanying drawings, which are given as an eXample-andin which: Fig. 1 is an eleva'tionof the machine.

Fig. 2 is a plan view of the same machine. Fig. 3 is a'view in cross section, made by a plane perpendicular to that of Fig. 1 and drawn to an enlarged scale. V Y

control The machine comprises a circulartable' 1 provided with a number of pockets 2 (eight in number inthe example repre- V sented), whose section corresponds with that of the lumps that it is desired to obtain. In each pocket a piston 3 is arranged to reciprocate with slight friction, the piston being connected byf rods Land cross head 5 to two rollers 6 arranged one on each side of the cross-head and adapted to roll in cams which .impart to them'vertical movements. The table 1 isrigidly connected to. driving gear 8 by means ofa hub 9, the. gear being of the kind adapted to. impart. tofthe table an intermittent rotary movement This device comprises a plate'S'furnished with slots (Fig. 5) for v engagementgwith rollers 46 mounted on. the control spindle 47.

The

immovable. This cam positions the wheels 7. at an. invariable height in frontof the compressing means which insures manufactured lumps of'a' uniform thickness.

For effecting the compression. of the manufactured mass as soon as it has been introduced into a pocket, the machine is provided'with the parts mentioned below. A filled pocket, in consequence of the displacement ofithetable 1 comes into a position immediately below a compressing cushion 18 which closes it completely by being superposed. Moreover, below the piston rods & and the cross-head 5 is disposed an arrangementpof bent levers 19, controlled by a connecting rod20 operated by means of a roller leverfllandflcam mechanism This control system-v imparts to piston 3' a vertical movement thereby compressing the. sugar infthe pocket. between the piston and. the cushion 18.; V

For effecting the discharge of the lumps after beingcompressed as described, the machine. comprises the following means. The lump;compressed'in a pocket moves into the receiving position by reason of the movement of'table 1.. When it is in. this position, the outer roller Gbfecorhes engaged in a groove-.,formed.in the lever 23, controlled by a system. of cams and the lump receives avertica-lirising movement so that itslower face. assumes a, position .at a level slightly aboye. thatrof ;an auxiliary conveying table The lump; is then pushed fontothis table by; a;blade- 25f controlled by a system of cams and by means of intermediate connecting rods andlevers- 26, 27, which are capable of parallel motion and cause the'blade 25 to slide the lump. during the displacement of the-latter; v

The. table 24: has the form of a regular polygon whose-sides correspondin number withthenumberof pockets ontable 1,, that is to say .eightinQthe illustrated example. It receives. an.. intermittent rotary motion, whichis communicated .to it by the wheel 2%, .for. the purpose, of moving the lump from the POSli'JlOIlrLL to. the position, b opposite: and. immediately above the conveyor plates.

When the lump. has arrivedin the position b.:a blade 28, controlled by the ,samesystem of. cams as .thi'e blade 25 above referred to, pushesthe lump, on the, conveyor, plates hich are carried alongby an endless. chain 29 actuateduwithia continuous movement. The chain is provided with claws or abuth n e d of the maeh e ih isn other part10 of'thecam is supported by the have 11'' which is fixed and remains lightly'in contact with the face of ,plying sugar to the for forming ments, 30 which 1 impelag the plates against which are distributed"thelumpsL, and is controlled by the drums31, 32-at the left and above drum 31, is arranged a magaz1ne83 serving forthe distribution ofithe plates 34. This magazine comprises four: vertical uprights 35 between which are piled the plates.

or lug on the endless'ch'ain which is 'pra The 5 lowest plate in the pileis dragged by a claw sented to, it opposite theleft'hand portion of;

he pile, The upper plates-remain between the set of uprights,thelower part of whi h the passage has the clearance necessaryfo'r of one single plate at a time.v When this plate has been'removed the plate immedi V ately above it takes its place, and the mega Zine automatically empties under gravitational action. The plates, as they arrive loaded with lumps L' atthe right hand end of the machine (Fig. 2), are lifted by hand. To ensure the cleaning of the pistonsof the pockets, these pass in succession, be-

tween the lump discharging positi-on and the pocket posit-ion, opposite: a cleaning device arranged as follows.

In the position definedabove, brought level' with the surface of table 1 the piston is and its upper part is. then swept by the cleansing arms 36, 37, which' are furnished with'rubber or other strips which'scrape the top end'of the" pistons, thearms receiving a continuous rotary movement: The arms are, moreover, adjustable means of a screw device so as to apply to the tops of the pistons pressure sufiicient'to ensure perfect cleansing.
